Title: In-situ diffusion of dopant impurities during dendritic web growth of crystal ribbon
Inventor: BATHEY BALAKRISHNAN R
IPC: C30B15/04
Filed: 1997-10-01
Abstract: A dendritic web formation process and apparatus for diffusing dopant impurities into a growing dendritic crystal web to produce photovoltaic cells. A solid dopant diffusion source is arranged in a holder mounted in a vertical thermal element either within the melt furnace or outside the furnace adjacent the furnace exit port. The solid diffusion source is heated by thermal conduction from the vertical thermal element and source holder using the furnace heat as a source.      Auxiliary heater coils are optionally provided around the vertical thermal element to control the temperature of the solid diffusion source. The source and holder can also be mounted outside the furnace adjacent the exit port and heated using a secondary rapid temperature external heater. The growing dendritic crystal web is exposed to the dopant impurities as part of the web growing process, eliminating the need for a separate diffusion gaseous station and processing.
Patent CA-2218279-A1 (CA)
Inventor: BYORUM HENRY
IPC: C23C14/34
Filed: 1996-04-23
Abstract: Système de pulvérisation (50) alimenté par une source de courant alternatif (59) dans la gamme de fréquence 10 kHz-100 kHz, comportant deux magnétrons cylindriques rotatifs (60, 62). Les magnétrons cylindriques rotatifs (60, 62), lorsqu'ils sont utilisés pour le dépôt d'une couche de diélectrique sur un substrat (80) enlèvent le diélectrique déposé sur la cible (64, 65), ce qui empêche la couche de diélectrique sur la cible (64, 65) d'agir comme un condensateur, et peut contribuer à éviter l'amorçage. De plus, un condensateur limiteur d'impédance (58) peut être placé en série sur le trajet électrique entre les cibles (64, 65) passant par le transformateur (54), de façon à réduire le risque d'amorçage. Ce condensateur limiteur d'impédance (58) a une capacité beaucoup plus élevée que le condensateur utilisé pour coupler l'alimentation électrique (59) à une cible (64,65) dans les systèmes de pulvérisation à radiofréquences.

Title: Cable drum type residential elevator system
Inventor: LANE JOHN R
IPC: B66B11/04
Filed: 1997-10-24
Abstract: A cable drum type elevator system for residential low-rise use.  The elevator includes: a vertically extending support-rail system,  an elevator cab mounted thereon for vertical movement, lifting machinery mounted to the support-rail system and cables operated by the lifting machinery and secured to the cab for raising and lowering the cab on the support-rail system.  The support-rail system is supported at its  lower end and secured to a ground position.   A foot assembly is secured to the rail support system and to the ground to cooperate in supporting the support rail system.          The foot assembly extends below the elevator cab.  The lifting machinery is mounted to the support rail system at its upper end.   A dampening system is used in the lifting machinery connection to the support-rail system to minimize system vibration due to the machinery.  A clutch-like braking system associated with the lifting machinery permits the elevator cab to be safely lowered to the next lower floor in the event of an external power failure to the lifting machinery.

IPC: D07B1/16
Filed: 1998-08-21
Abstract: A portable safety sheath for wire rope cables is disclosed. A narrow strip of strong fabric has a series of fasteners along its long edges. The fabric strip may be wrapped around a cable being used with an implement such as a winch, and the edges of the strip may then be connected using the fasteners, such that the fabric strip forms a continuous sheath around the cable. In the event that a strand of the cable should rupture while the cable is under tension, the sheath surrounding the cable will absorb the energy released by the rupturing strand, preventing the broken strand segments from whipping outwardly from the cable. After use, the safety sheath may be easily removed from the cable, then folded or rolled up for convenient storage or transport.

The invention comprises using a coating colour which contains pigments having a steep particle size distribution, a maximum of 35 % of the pigment particles being smaller than 0.5 ~m. The coating colour is spread on the surface of the web with a coating speed of at least 1450 m/mir, preferably over 1600 m/min The coating pigment having a steep particle size distribution gives rise to a coating colour which solidifies at much lower dry substance than conventional coating colour. In this way coating can be controlled at high speed without renewability and quality problems.
